Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596964, here are decompositions:

41 + 31596923 = 31596964
83 + 31596881 = 31596964
107 + 31596857 = 31596964
167 + 31596797 = 31596964
251 + 31596713 = 31596964
257 + 31596707 = 31596964
293 + 31596671 = 31596964
353 + 31596611 = 31596964

Showing the first eight; more decompositions exist.
